Efficacy and safety of robotic liver surgery for the elderly: A propensity‐score matched analysis of short‐term outcomes with open liver surgery at a single center in Denmark

Background The incidence of liver tumors requiring surgical treatment continues to increase in elderly patients. This study compared the short‐term results of robotic liver surgery (RLS) versus open liver surgery (OLS) for liver tumors in elderly patients. Methods A prospective database including all patients undergoing liver surgery at Copenhagen University Hospital between July 2019 and July 2022 was managed retrospectively. Short‐term surgical outcomes of the two main cohorts (OLS and RLS) and subgroups were compared using propensity score matching (PSM) in elderly patients (age ≥ 70 years) with liver tumors. Results A total of 42 matched patients from each group were investigated: the RLS group had significantly larger tumor diameters, less blood loss (821.2 vs. 155.2 mL, p
